The components of my robot are 2 DC motors,a L293DNE H bridge,and the beloved Arduino UNO board.There are 2 infrared LED's in the front,and 2 fototransistors near them.On the board with the driver are also two voltage dividers for suplying the fototransistors.The infrared sensors are connected on A0 and A1,and the L293D is on A2,A3( left motor) and A4,A5(right motor).
Hi,thx for the advice.I mounted the wheels on the motors with termocontractable tube.The bad part on my project is that it doesn’t have a gearbox.The wheels are connected to the ax.I controll speed only by the software.I think i will move the arduino board on the other side to be protected.
Thank you chuck! i think i will buy a gearbox like that one.My driver is almost the same,the curent is about 600 mA.With a gearbox it will be even lower.
